You understand that discovery requests as you made only applies to documents that exist. If the officer didn't prepare a report at the time, he's not required to generate one now. If they were a two-man patrol, likely only one of them prepared a report. I have no clue why an LP guy would write a "police report." He's not the police. Anyhow, LP is generally allowed to detain suspected shoplifters, not sure why you're getting bent over the report. The person who detained you admitted to the detention, there's nothing the cops are going to add. They didn't witness anything other than that you were in custody. Nothing they can say about the thing is admissible in court (except perhaps for your own incriminating statements).

If you were charged with something you better get your butt to the lawyer. I'd stop admitting publicly to your participation in federal felony crimes.
